ABS light

[Dirtclod]

I'm going to install new brake pads on my 01 F250 this morning. When I did the seals in the axle and hub I must've got something wrong when I put it back together. My abs light stays on and it's not working right. Sometimes when I push down on the brakes the back ones lock up. ANy ideas on how these get installed?

Abs sensor is held on by one screw. I had to replace mine because it went bad when the hub crapped out on me. Not hard to do at all, less than 10 minutes to do both.
